Analysis compares two policy options for vehicles already on the road — 250 million in the U.S. and 900 million globally — that will continue to burn fossil fuels for decades. Large-scale, properly tuned policies can substantially reduce these vehicles’ carbon footprint. Two solutions focusing on older low-efficiency vehicles are scrappage programs, which are gaining increasing support in many countries, and conversions to plug-in hybrids (PHEVs) and all-electric vehicles (EVs), an emerging new option.
